"Beating Heart" is a song recorded by English singer and songwriter Ellie Goulding for the soundtrack to the film Divergent (2014). The song was written by Goulding and Joe Janiak, and produced by Greg Kurstin. It was released on 9 May 2014 as the second single from the album.

British singer-songwriter Joe Janiak wrote the original version of "Beating Heart" on banjo in 2012. He took inspiration from dropping off his American girlfriend at the London airport, before Goulding heard the song and reworked some of the lyrics. On 23 January 2014, it was confirmed that Goulding's "Beating Heart" would be included on the soundtrack to the 2014 film Divergent, based on the dystopian novel of the same name by Veronica Roth. According to Divergent director Neil Burger, "We started working on the film with songs from Ellie Goulding's album Halcyon and soon found that the texture of her music and the tone of her voice matched perfectly with our film." In an interview with Matt Lauer on the American morning television show Today on 12 March, Goulding said, "I had the song, and I performed it and recorded it, and I had given it to Greg Kurstin to produce it. I didn't know they were gonna use it for the film, but actually, when I thought about it, I thought it was kind of perfect, and it really suited the whole theme." The song plays over the end credits of Divergent.

While filming the music video for "Beating Heart", Goulding told MTV News that the song is about "being away from someone or knowing that you're always going to have to be apart from someone that you really love." She added, "And it's painful, but it's hopeful because there's always a chance that they'll collide again like two people collide. Like the universe will bring them back together. I think the song is basically that. Sort of relying on the fact that if you're meant to be drawn back together you will be."
